indhub opened a new issue #11442: No module named 'dmlc_tracker' URL: https://github.com/apache/incubator-mxnet/issues/11442 ## Description `pip install mxnet-cu91` (or `mxnet-cu90`) does not install dmlc-tracker. Running distributed training after pip install gives this error ``` ubuntu@ip-172-31-33-187:~$ mxnet/tools/launch.py -n 2 -s 2 --launcher local python cifar10_dist.py Can't load dmlc_tracker package. Perhaps you need to run git submodule update --init --recursive Traceback (most recent call last): File "mxnet/tools/launch.py", line 128, in <module> main() File "mxnet/tools/launch.py", line 96, in main args = dmlc_opts(args) File "mxnet/tools/launch.py", line 48, in dmlc_opts from dmlc_tracker import opts ImportError: No module named dmlc_tracker ``` The error goes away if dmlc-core is built separately and PYTHONPATH is set correctly. After `pip install mxnet-cu`, shouldn't users be able to run distributed training without any more installations? ## Environment info: Ubuntu p2 instance Package used (Python/R/Scala/Julia): 1.2 ## Steps to reproduce (Paste the commands you ran that produced the error.) - Create an instance with 4 or more gpus. - wget https://raw.githubusercontent.com/indhub/mxnet/e5b89cf9d7c35ac749ed14b54c0faa6dfffa15ef/example/distributed_training/cifar10_dist.py - mxnet/tools/launch.py -n 2 -s 2 --launcher local python cifar10_dist.py
